Abstract:The primary objective of a long-term research program at West Virginia University was developing design criteria for bond in reinforced concrete for both the ultimate- and service-load conditions. These design criteria have been based on a comprehensive experimental research plan that included a study of the influence of reinforcing bar embedment length and spacing, stirrups, concrete cover and associated concrete strength, and the interaction of shear and flexure on bond behavior. The project used a new cantilever, or stub beam, specimen that is thought to be a considerable improvement on the conventional pullout specimen. A design equation suitable for ultimate load design has been developed. In addition, cracking loads have been considered as a separate limit state.
